I have been searching high and low for some more advanced npc creation tutorials and coming up empty. I want to give my npc some spells that I created, but simply putting in their spell list is not enough to get them to use it. What piece of the puzzle am I missing? I heard whispers that perhaps I need to alter their combat behavior, and reverse engineering follower mods that use custom spells leaves me overwhelmed.

Could you please point me in the right direction? I would be very grateful.
